Excellent analysis, Joe.
From the point of view of psychology, I see another side to this.
My first thought was that these people don't really believe any of that. They don't believe - not gut deep - that their jobs are threatened by more geniuses. Where is this flood of geniuses coming from? Are they popping up out of the ground like mushrooms after a rain? Or, falling from the sky?
No one starts becoming seriously concerned about something that isn't happening or going to happen, or is said to possibly be happening at sometime. Now, if on the news, there was an announcement that we were going to drastically change our immigration policy to open the door wide, and even pay people to emigrate, but only if they were geniuses. And we expected this new policy to be wildly successful, then we would need to see your article was given wide circulation because then there WOULD be people who mistakenly feared financial woes - and those people would be happy to learn that things would be better, not worse.
But in the absence of it threatening to rain geniuses, there is something else going on and I smell rationaliztion, denial, and projection.
People are often resentful of virtues and values specifically for being virtues and values. The reason for such a strange reaction is that they have betrayed some of their own virtues or turned their back on certain values... maybe out of fear, or even just laziness. They can ignore, to a degree, the psychological consequences of those acts as long as they can turn away from whatever might symbolize that which they betrayed.
Each person who comes into view as energetically productive will often earn the ire of the cynically lazy who wants to settle for less in his life but also wants others to do the same, and doesn't want to have that productive person out there that he can be compared to.
Another unpleasant pattern is where those who out of a represssed fear of not being up to whatever challenges tomorrow might bring, end up building an emotional safety-nest out of anti-change beliefs. They fear and resent those who might bring about change. They have an implicit sense that they are getting by just fine as long as no one upsets the status quo. This is often why people with above average intelligence, and people who are exceptionally productive, are subjected to messages to back off, to take it easy, don't get too big for your britches, leave things well enough alone, don't rock the boat, who are you to think you know better, put in your dues first, respect tradition, etc.
Certainty in one's approach to work isfelt like an affront to some who feel uncertain and want a comfort of fog and keeping things the same.
Whether it is intelligence, productivity, confidence, honesty, or success... there are those who don't want to hear why more individuals with these are good for everyone, not just for the person who shines. They won't be honest with themselves about why they feel negative towards those virtues and values, but the fact is that they WILL be very open to rationalizations, denials, to sharing their hostile attitudes with those they feel akin to, and they will displace the negative feeling they should have for what they did to their life onto others that symbolize what they should have done with their life.
